MILK CAN OPENER Filed Oct 12, 1955 2 Sheets-Sheet 2 3 [nvenlor "m" IPli'hrd je km ve A 110 may Patented Aug. 25, 1936 UNITED STATES PATENTOFFICE MILK CAN OPENER Richard De Trempe, Kenney, Ill. ApplicationOctober 12, 1935, Serial No. 44,779 4 Claims. (01. 164-11 9) Thisinvention relates to a. device for punching holes in milk cans and thelike so that the contents can be poured therefrom, the general object ofthe invention being to provide a clamp for encircling the can, levermeans carried by the clamp and punch means for punching two holes in thecan topwhen the lever means are actuating.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which:-

Figure 1 is a fragmentary elevation showing the invention attached to acan.

Figure 2 is a top plan view of Figure 1.

Figure 3 is a fragmentary side view of the clamping member showing thelever in open position.

Figure 4 is a top plan view of the clamping member in open position andwith parts in section.

Figure 5 is a section on the line 5-5 of Figure 2.

Figure 6 is a section on the line 66 of Figure 2.

Figure 7 is a view of the short lever which carries one of the punchers.

Figure 8 is a view of the link which connects this lever with the mainlever.

In these drawings the numeral l designates a spring metal strap whichhas a hinged leaf 2 fastened to one end thereof which receives the hingepin 3 which hinges theclamping lever 4 to said end of the strap I. Thislever 4 has its upper and lower edges bent to provide the flanges Iwhich are slotted as shown at 8 through which pass the bent ends 9 ofthe extremities of the limbs of a yoke ll] of flexible wire or the like.The yoke has its limbs through holes in the bent part II of a plate 12fastened to the other end of the band or strip I. When the clamp is toengage large cans the bight of the yoke engages the part II but whenused on small cans the bight of the yoke is placed over the book [2'which makes the clamping device of smaller diameter. A sleeve 13 isplaced between the flanges 1 and receives the bent ends 9 and a pair ofsprings I4 are connected with the ends 9 at the ends of the sleeve andthe other ends are connected to the lever 4 as shown at I5. Thus whenthe band or strip l and the yoke ID are in open position as shown inFigure l and placed around a can such as shown at A in Figure 1 it issimply necessary to swing the lever 4 to the left in Figure 4 and thisaction of the lever will contract the parts I 5 and E El around the canand thus firmly attach the parts to the can. As will be seen the springsM will exert a pull upon the extremities of the limbs of the yoke l 0 soas to yieldingly hold the member around the can which arrangement alsoprovides means whereby the device can be placed around cans of differentsizes.

A casing B has a depending part IE on its bottom l8 which is riveted toa part of the strip l as shown in Figure 4 and said casing includes the15 sides [9 which project beyond the depending part It. A main lever hasa substantially inverted V-shaped end portion 2| the extremity of whichis hinged to the outer ends of the sides I9 as shown at 22 and saidlever is formed with a sub- 2 stantially straight intermediate portion23 having an elongated longitudinally extending slot 24 therein, therest of the lever being slightly offset upwardly as shown at 25 toprovide a handle portion. A punch 26 has a threaded stem 28 25 passingthrough the slot with the punch held in adjusted position by the nut 29.A short lever 30 is pivoted at the inner end of the casing B as shown at3| and this lever carries the second punch 32 which is held in place bya nut 33 and. 30

the bottom I 8 of the casing is provided with an opening through whichthe punch 32 passes. The free end of the lever 30 is bent upon itself toprovide an eye and the stem of the punch 32 and the nut 33 holds thebent part in place and a link 34 pivotally connects the free end of thelever 30 with the ear 35 depending from the part 2| of the main lever20.

Thus it will be seen that the device can be firmly attached to the upperportion of a can and then by swinging the lever 20 downwardly the link34 will swing the lever 30 downwardly so that the punch 32 will punch ahole in the top of the can and then upon continued downward movement ofthe lever 20 the punch 26 will punch another hole in the can top so thatthe top will be provided with a pouring hole and a hole for admittingair into the can.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts provided 5 thatsuch changes fall within the scope of the appended claims.

What is claimed is:-

l. A device of the class described comprising a lever, means fordetachably connecting the lever with a can, a punch carried by one partof the lever, a second lever, a punch carried thereby and means forfirst causing the second punch to punch a hole in the can top when thefirst lever is swung downwardly and then to cause the first punch topunch a hole in the can top.

2. A device of the class described comprising a clamp band forencircling a can, a lever, means for pivotally connecting one end of thelever to a part carried by the band, a punch carried by a part of thelever, a second lever pivotally supported from a part of the band, asecond punch carried thereby, a link connecting the second lever with apart of the first lever whereby downward movement of the first leverwill cause the punch of the second lever to first punch a hole in thecan top and then the punch of the first lever will punch a hole in thecan top.

3. A device of the class described comprising a clamping band, a levermoving the band in clamping and unclamping position, a casing having adepending part connected with a portion of the band, a main leverpivoted to a part of the casing, a short lever pivoted in the casing, alink connecting the short lever with the main lever at a point close tothe pivotal point of the main lever, a punch carried by the short lever,a punch adjustably carried by the main lever.

4. A can punching device comprising a clamping band, means for adjustingthe length of the band, a lever for adjusting the band in clamping andunclamping position, a main lever pivotally connected with a part of theband, a pair of punches and means operated by the main lever for causingsaid punches to penetrate the top of the can which is encircled by theclamping 2 band.
